`To (J/,Zlwlwm t may con/cern:

Be it known that', LEE T. Amon, a citi- Zen of the UnitedStatesvand a resident of the Icity ofy New York, borough of Brooklyn,

county of Kings, and State of l\lew Y0rk,` have invented a new and useful Improvement in Incandescent Gas-Lamps, 'of which the following is a specification.

' The Aobject of `my invention is 'to-provide an article of. this class which will lproduce light more lefficiently-that is, for a V given y consumption of gas it will produce more light or heat than any other burner'known -to me which receiyes the same amount vof gas. This object has been accomplished after numerous experiments, by providing a check and air-mixing chamber of a vpeculiar form,

k*and also by providing an additionalhairchamber which surrounds the mixing-channfiber and permits thel supply of pure aire-that y is, air free from gas-to be directed against the' inside of the mantle in predetermined quantities, whereby a more complete combustion is had, and a larger mantle may, be heated either to incandescence, if. the mantle is to. be used for lighting purposes, or to a i lower degree of temperature if the burneris ole'sired'for heating purposes only.

" For a more particular description of my a sectional view taken on the line 2l 2 Yof Fig.

which is adapted to be iiXed to a gas-pipe.

surmounted by the mixing-chamber 4 kand gallery '5. A wire 6 extends from the gallery a Way; and surrounding the' mixingfchamberv 4 and extending into the mantle? is the tube l53,

which is preferably made concentric the mixing-chamber 4, so that' yfacham 'erris formed between the walls" of the chamberfj4 and'the tube 8.

' ards 25,'Which are united attheir upperends and then iiared upwardly and'-outwardly'7'*a1-J 2,6 to form a portion of thewallslof thelairiiilet `chamber 23.` l Thesewalls are perforated, asishown yat 2.7, andthe check preferablyexn tends y:about two-.thirds ,the length k,of-ithese openings. Surroundingv thev "curved portion 26l is a 'damper or shutter 28, whichhas:per-y foration's v29, adapted"to"register vwithnthe openings `27 or to partially close them,`as ih'ay y"be desired. Thisis` accomplishedfby turning the knurled flange 30 attheupper vez'ctr'eniity ,Of thisshutterfQS. I 'A lug or lugs 31,"piefervably integral with and bent from the uprights 25 secure thisishutterin place, as is evident `inFigi 7. Thelower'portion ,26"ofthe'airinletlchamber 23'is surmounted bythe domevshapledupper portonji32,` which is connecter'l` to t . e raft 23. 'by' means bf"flener33tlrd collarl 34, as is apparent Figr 15g Inpifgl@ loo tice`the parts 32 and 33 of the air-inlet chamber may or may not be pressed together at the volition of the manufacturer, the brazed structure for most purposes being preferred. The dome 32 is surmounted by a short tube g 35, which extends upwardly and which retains and holds a short tube 36, which may be made as long or short as desired, although to secure the best results all parts should be made in the proportions indicated in Fig. l. As is obvious, the tube 36 may be screwthreaded in the part 35 or brazed therein or held in any other suitable way, as desired.

Bothy the tubes 35 and 36 are surrounded by another tube 37, to which is secured the gallery 5. This gallery extends upwardly in the usual manner and is surmounted by the disk 38 and chimney-retaining iingers 39. It is also provided with the usual support for the mantleewire 6, which'includes'the setscrew 40 and the casing 4l therefor, as well as the necessary perforations therethrough and through the disk 38. With the exception of the disk 38 this construction of gallery is old,

so that a more detailed description is believed to be unnecessary. The disk 38 diTers from the ordinary disks on galleries in that except for the center bore and the perforation for thepassage of the wire 6 it is imperforate and does not extend to the mixing-chamber. 4, but terminates at the tube 8 and is provided with l,a downwardly extending flange 42, which rests snug against the tube 8 and preferably forms therewith an air-tight joint, the purposes of which will appear below.

Surrounding the tube 37 and snugly fitting against its lower portion is another tube 43, which is provided with an integral iange 44 and is screw-threaded at its upper end to receive the mixing-chamber 4, as shown in Fig.

1. A collar 45 rests on the flange 44, and this collar 45 is suitably knurled and provided 'with radiallyeextending teeth 46, which run at right angles to the' knurled portion. These teeth have openings between them which are adapted to register with corresponding openings formed by teeth 47, which extend from the lower edge of the mixing-chamber 4, and above these teeth 47 the mixing-chamber 4 is slightly enlarged, as shown at 48, and then extends in a cylindrical form to its upper extremity.

The interior of the mixing-chamber 4 is preferably provided with one or more gauzes 49, and its upper extremity is provided with a gauze 50, which is preferably set in a small annular recess 51, so as not to interfere with the smooth exterior surface of the chamber 4. The gauzes 49 may be omitted entirely, if desired, but if omitted the burner loses some of its efficiency. The tube 8 rests on the projections 47 and extends up therefrom through the flange-opening in the disk 38 to the plane of the upper end of the chamber 4, where the tube 8 is provided with a top 52, which is perforated, so as to break up the air which passes through the tube 8 into a plurality of small streams. The mantle 7, as described above, is mounted in the usual way, as indicated in Fig. l, and surmounts the burner and surrounds the upper extremity of the tube 8.

From the foregoing the operation of my improved burner will be evident. Gas passes into the check, as indicated by the arrow a at the bottom of Fig. l, and at the upper extremity of this check it is somewhat mixed with air which passes as indicated by the arrows l), as well as through the openings in the lower end of the check. As the gas issues through a number of small perforations it is finely divided, and as its pressure is reduced it readily expands against the wall of the air inlet chamber, and as it rises it comes in contact with the lower edge of the tube 3G, against which it is forced by the contraction of the dome 32, and the mixture is made more complete. The mixing-chamber 4, together with the screens or ganzes 49 and 50, makes this mixture as complete as possible, and when it issues from the gauze 50 the mixture may be burned. in the usual way with more than the ordinary e'l'lieiency. However, I have found after exhaustive experiments that by incasing the mixing chamber 4 in the tube 8 an air-inlet chamber is formed bctween them, so that pure or unmixed air issues in a finely-divided state through the perforated top 52 at the upper extremity of this tube, and the air from this chamber further unites with the iiame at the top of the gauze 50 and produces a very complete combustion through the mantle 7, which readily heats it -to incandescence. The amount of air best suited to produce this combustion is regulated. by turning the knurled collar 45, and by turning the damper 28 and cap 19 the air and. gas mixture in the mixing-chamber 4 may also be varied, so that by trial and adjustment the best results may be obtained. By experiment I have found IOO IOS

that a large mantle may be heated to incandescence in this way with the same amount of gas that is required for a smaller mantle that would ht the mixing-chamber 4.

Vhile any ordinary style of chimney or globe may be used with my burner, as above' described, I prefer that the type of chimney with holes on a level with the mantle should be employed, as this chimney with this burner appears to give the best satisfaction.

While the burner as described above obtains the best results, it is obvious that all its features need not be utilized on the same burner. For example, the mixing-cha1nber and its inclosed tube may be used with any other form of check and air-inlet chamber than the one shown. Therefore I do not regard my invention as limited to the precise combination herein shown and described, but regard it as broad enough to cover all ing the mixing-tube, a jacket inclosing the mixing-tube and extending through the top gallery to the upper part of the mixing-tube,

and an annular air-shutter encircling said tubular member and commanding the said lower end of the jacket. v
